Currently Teaching

IMGS-261
Linear and Fourier Methods for Imaging
4 Credits
This course develops the concepts of complex numbers and linear algebra for describing imaging systems in the frequency domain via the discrete and continuous Fourier transforms.
IMGS-322
Physical Optics
3 Credits
Light waves having both amplitude and phase will be described to provide a foundation for understanding key optical phenomena such as interference, diffraction, and propagation. Starting from Maxwell's equations the course advances to the topic of Fourier optics.
IMGS-617
Image Processing and Discrete Fourier Methods
2 Credits
This course considers sampled and quantized images and temporal image sequences, along with methods for performing useful image processing. These processing methods are classified based on the number of input picture elements (“pixels”) that determine the value of each output pixel: single pixels, local neighborhoods, or global operations. The discrete Fourier transform is introduced. Application to image segmentation and compression are considered.
IMGS-633
Optics for Imaging
2 Credits
This course describes Fourier transform of continuous functions, followed by its application to describe optical imaging systems in the wave model, including the concepts of point spread function, optical transfer function, and image resolution. Analysis of optical imaging systems using the ray model for systems composed of one thick lens and two thin lenses are considered.
IMGS-799
Imaging Science Independent Study
1-4 Credits
This course is a faculty-directed tutorial of appropriate topics that are not part of the formal curriculum. The level of study is appropriate for student in their graduate studies.

    RIT innovation helps illuminate lost history

    The goal of libraries, museums, and archives around the world is to safeguard historical documents, but some objects can deteriorate with time. RIT’s Cultural Heritage Imaging (CHI) lab is using funding from the National Endowment for the Humanities to develop a relatively low-cost system that makes cultural heritage imaging methods more accessible.
